The number of watts it will consume is 436.32

A light bulb consumes 2400 watts/hour

The number of watts it will consume in 5 days 12 hours can be calculated as follows

The first step is to change 5 days 12 hours to hours

120 hours + 12 hours

= 132 hours

The bulb consumes 2400 watts per hour

= 2400/132

= 18.18

The number of watts consumed in 5 days 12 hours is

= 24 × 18.18

= 436.32

Hence the light bulb will consume 436.32 watt-hour in 5 days 12 hours

After the conversion, we get T² = 1/3 A

It is given that

T = [tex]A^{\frac{3}{2} }[/tex]

We have to convert the equation without rational exponents

T³ = A²

1/2 T = A³

T² = A³

T² = 1/3A

The probability that it will be a blue highlighters is 3 / 10.

In statistics, what does a probability mean?

the highlighters which are dried up and will not write or eight

number of red highlighters = 10

number of blue highlighters 15

number of green highlighters = 5

number of yellow highlighters = 10

therefore the total number highlighters in the box

= 10 + 10 + 15 + 5 + 10 = 50

probability of Blue = number of blue highlighters

Total number of highlighters

= 15 /50 = 3/10 = 0.3

Step-by-step explanation:

The probability that you will not go on to a career in physics is 0.215.

From the information, the test is so tough that anyone not going on to a career in physics has no hope of passing, whereas 55% of the seniors who do go on to a career in physics still fail the test and 75% of all senior physics majors in fact go on to a career in physics.

Therefore, the probability that you will not go on to a career in physics will be:

= (1 - 0.75) / (0.75 × 0.55) + (0.75)

= 0.25 / (1.1625)

= 0.215

Therefore, the probability that you will not go on to a career in physics is 0.215.

Step-by-step explanation:

a square 4*4 : wide=4 , lenght=4

number of rectangles= wide*(wide+1)*lenght*(lenght+1) /4 = 4*5*4*5/4=100

Proof:

1 per 1 : 16 (rectangles )

1 per 2: 3*4=12

1 per 3: 2*4=8

1 per 4: 1*4=4 so 4*(4+3+2+1)=4*10=40

2 per 1: 4*3

2 per 2: 3*3

2 per 3: 2*3

2 per 4: 1*3 so 3*(4+3+2+1)=30

3 per 1: 4*2

3 per 2: 3*2

3 per 4: 1*2 so 2*(4+3+2+1)=20

4 per 1: 4

4 per 2: 3

4 per 3: 2

The confidence limits for the proportion of consumers motivated by advertising in the population, given a confidence level equal to 0.95. is; CI = (0.47, 0.77)

We are given;

Sample Size; n = 60

sample proportion; p' = 65% = 0.65

Confidence level = 0.95

Now, formula for confidence interval of proportion is;

CI = p' ± z√(p(1 - p)/n)

At CL of 95%, z = 1.96Thus;

CI = 0.65 ± 1.96√(0.65(1 - 0.65)/60)

CI = 0.65 ± 1.96√0.00379167

CI = 0.65 ± 0.12

CI = (0.65 - 0.12), (0.65 + 0.12)

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

Let's say Allison and Caleb's height in the photograph is A' and C' while in actuality it is A and C.

Since the ratio of height in the photograph will same as the ratio in actual life.

Thereby,

C/A = C'/A'

C/60 = 3.2/4

The computation shows that the tons of sugar when they'll have same price is 18 tons.

The first company charges $5500 to rent trucks plus an additional fee of $200.25. Thai will be:

= 5500 + (200.25 × s)

= 5500 + 200.25s

where s = tons of sugar

The second company charges $5041 to rent trucks plus an additional fee of $225.75 for each ton of sugar. This will be:

5041 + 225.75s

Then we will equate both of them. This will be:

5500 + 200.25s = 5041 + 225.75s

5500 - 5041 = 225.75d - 200.25s

459 = 25.5s

s = 459/25.5

s = 18

From the union operation between sets, we have that the number of elements for each case will be as follows:

a) 11069.

b) 9975.

c) 11031.

The union operation between sets is the set that contains all elements that belong to at least one of the sets.

In item a, if the sets are disjoint, all the elements belong to only one set, and the number of elements in A1∪A2∪A3 is given by:

102 + 992 + 9975 = 11069.

For item b, if they are all contained into A3, the number of elements is the cardinality of A3, given by 9975.

For item c, we have that:

Hence:

n(A1∪A2∪A3) = 4 + 3 x 10 + 78 + 968 + 9951 = 11031.

The required number of people that are in the US labor force is 0.0086t² + 0.087t + 25.375.

To determine the total number of people available in the US labor force.

In mathematics, it deals with numbers of operations according to the statements.

Here,
As per the data available, the number of Men in the US labor force is M = 0.0016t² + 0.315t + 19.467 and the number of women are W = 0.007t² -0.228t + 5.908.
Total people available in the US labor force,
= Number of women + number of men
= 0.0016t² + 0.315t + 19.467 + 0.007t² -0.228t + 5.908
=  0.0086t² + 0.087t + 25.375.
